Description: Sodium fluoride is an ionic compound commonly used in a a variety of gels, varnishes, rinses, toothpaste products, and fluoride treatments provided in dental care. It has a relatively high melting point of 993 degree celsius and a boiling point of 1695 degree celsius, higher than sodium chloride as it has one less electron shell, meaning electrostatic forces of attraction are not that strong, causing less heat to break the bonds of NaCl compared to NaF. It is also a slight conductor of electricity as it contains a metal, sodium which is an electrical conductor, meaning that all ionic compounds should be electrical conductors in molten or aqueous state.
